This part of GB/T 12796 specifies the scope of water magnetic ferrite magnets (hereinafter referred to as "magnets") The quality assessment procedure includes the selection of test items and measurement methods, as well as relevant units, symbols, and terms, in accordance with the specifications and blank detailed specifications. There are also rules for writing blank detailed specifications. This section is applicable to isotropic and anisotropic magnets for devices such as electroacoustic, telecommunications instruments, instruments, vacuum devices, microwave devices, micro special motors, magnetic separation equipment, adsorption equipment, magnetic machinery, magnetic seals, etc., including bonded magnets. The following normative references are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modification orders) applies to this document.
